Answer:

Step-by-step explanation:

We need a system of equations here, 2 equations for 2 unknowns. The unknowns will be x and y and will represent the rates of 2 mechanics. The first equation will relate the 2 mechanics' rates and the second will involve the total they charged at their respective rates having worked a specific number of hours on the car.

We are told that the 2 rates added together was 170 per hour, so the first equation will be

x + y = 170

The next equation will be the rates times the number of hours worked:

10x + 15y = 2175 This means that the mechanic charging x dollars per hour worked on the car for 10 hours, and the mechanic charging y dollare per hour worked on the car for 15 hours, and that the amount this added up to was 2175.

We solve the first equation for y, just because. You could also solve it for x, if you want. Doesn't matter; you'll get the same answer either way.

y = 170 - x and sub that for y in the the second equation. Then we will have an equation with only 1 unknown in it:

10x + 15(170 - x) = 2175 and

10x + 2550 - 15x = 2175 and

-5x = -375 so

x = 75. One mechanic, the one who worked for 10 hours on te car, charges 75 per hour. To find out how much the other guycharges, go back to the first equation and sub in 75 for x:

75 + y = 170 so

y = 95 per hour.

Answer:

C i think

Step-by-step explanation:

Answer:

y varies as the x², y=200 when x=5

Step-by-step explanation:

y=(k)x

200=(k)5

200/5=40

therefore; y= -120 because

y=(40)-3

y=-120

Answer:

$129.44

Step-by-step explanation:

15% of $212.50 + 15% of $235.00 + 15% of $215.75 + 15% of $199.67 =

= 0.15 * $212.50 + 0.15 * $235.00 + 0.15 * $215.75 + 0.15 * $199.67

= $31.88 + $35.25 + $32.36 + $29.95

= $129.44

Answer: $129.44

Answer:

16.5

Step-by-step explanation:

20.5 = x + 4

16.5 = x

x = 16.5

Answer:

x = 16.5

Step-by-step explanation:

20.5 = x + 4

20.5 - 4 = x + 4-4

Answer:

1/3

Step-by-step explanation:

7 + 6 + 8 = 21 (There is a total of 21 marbles)

There are 7 red marbles, so the fraction should be 7/21 or 1/3

Have a great day :)

Answer:

1/3

Step-by-step explanation:

How I got this answer is by adding 7+6+8 and I got 21. Then, I put the total of all of the marbles as the denominator which is 21. Next, I put 7 as the nominator so the fraction would be 7/21. Finally, I simplified 7/21 by 7 and I got 1/3.

Answer:

We have a rectangular prism of measures:

(2 + 1/4)ft by 9ft by 4ft

Let's analyze each one of the statements:

a) The base is a square?

A square has the same length as the width, this prism would have a square base if at least two of the dimensions are equal, but we can see that are all different, so we can conclude that the base can not be a square.

b) The volume of the rectangular prism is 81 cubic feet?

The volume will be equal to the direct product of the 3 dimensions, then the volume is:

V = (2 + 1/4)ft*9ft*4ft = 81 ft^3

This statement is true.

c) The area of the base is 36 square feet.

We know the dimensions, but we do not know which ones describe the base.

In the usual notation, the first two measures will describe the base of the figure, and the third one is the height.

Then the area of the base is:

(2 + 1/4)ft*9ft = 20.25 ft^2

The area of the base is not 36 ft^2

d) if you doubled the height, the volume would be the same:

Of course if we double one of the dimensions the volume will change, but let's calculate this.

The original height is 4ft, if we double this, the new heights Is 2*4ft = 8ft

Then the new volume will be:

V = (2 + 1/4)ft*9ft*8ft = 162 ft^3

The volume changes.

Manuel reads 3/4 chapter in 4/5 hours.

Rate = Chapter / Hours

Rate = (3/4) / ( 4/5)

Rate = 0.75 / 0.80

Rate = 0.9375

So, Manuel reads the chapter with rate 0.9375 chapters/hour.

Well t has to be zero, for r+t to equal r itself. so -s is equal to r, because it's r-0. Answer is C

Answer:

1533g

Step-by-step explanation:

We know 2 apples weigh approximately 511g.

If we multiply this by three, we'll find the weight of 6 apples (because 2x3=6):

511x3=1533

Answer:

65 r 9

Step-by-step explanation:

First we see what 7 divided by 11 is, we know that it is 0 so we put it in the top as our first number then we subtract 0 from 7 which is 7, then we bring down the 2 to make our next number 72, now we see if 11 can go into 72 and we know that it can by 6, we put our six on the top and then multiply it by 11 to get 66, we subtract our 66 from 72 to get 6, we bring down the 4 to make 64 and divide it by 11 to get 5 which we put on the top, then multiply 5 by 11 to get 55, subtract 55 by 64 to get 9 and because now there's no more numbers in the sum, 9 is our remainder.

Answer:

the answer is 575.12

Step-by-step explanation:

since the mortgage amount is $164320, you divide that by 100 because it is $100 per $.35.

lastly, you multiply it by .35

you should have something like this: 164320/100x0.35

which equals 575.12.

Answer:

Step-by-step explanation:

just a guess, it seems like you are asked about only dimensions of the big one, isnt that just 2/3 of 2700 km2. that is 1800km2 which = 60 km x 20km.

Answer:

All kinds of questions since you don't describe the enclosures.

Do the two fields have the same width?

Are there two disjointed fields with the same width and one length twice the other?

If they are joined by a common width, is that common width included in the total perimeter?

I guess this is d answer=60km×30km

To Prove :

a×(b+c) = a×b + a×c

Solution :

Solving L.H.S. we get :

[tex]a(b+c ) = \dfrac{1}{3}( \dfrac{1}{5}-\dfrac{2}{3})\\\\= -\dfrac{7}{45}[/tex]

Solving R.H.S. we get :

[tex]a\times b + a\times c = \dfrac{1}{3}\times \dfrac{1}{5} + \dfrac{1}{3}\times (-\dfrac{2}{3})\\\\= -\dfrac{7}{45}[/tex]

Since, L.H.S = R.H.S

Therefore, the given equation is correct.

Answer:

The formula for percent change is [tex]\frac{new-old}{old}(100)[/tex]. Because she scored 13 points and scored 22 points in the next game, the new value is 22 and the old value is 13. Plug in the values to get [tex]\frac{22-13}{13}[/tex] or [tex]\frac{9}{13}(100)[/tex]. Multiply the values to get 69.23 or 69.23%.

Answer:

The ball is 3.86 meters from the wall when it stops rolling.

Step-by-step explanation:

Representation of the situation:

This situation can be represented by a right triangle:

The hypotenuse is the distance the ball traveled, of 6 meters.

The distance from the wall is the side opposite to the angle of 40º.

We have that:

Sine of an angle is the length of the opposite side divided by the hypotenuse. So, in this situation.

Sine of 40 degrees = Distance from the wall/6

Sine of 40 degrees is of 0.64278760968.

Distance = 6*0.64278760968 = 3.86.

The ball is 3.86 meters from the wall when it stops rolling.

Answer:

the table should show the data

Answer:

b = 4 inches and h = 14 inches

Step-by-step explanation:

Given that,

The area of a triangle, A = 28 sq inches

Height is twice less than 4 times the base.

H = 4b-2, b is base

We know that,

The area of a triangle is given by :

[tex]A=\dfrac{1}{2}bh\\\\28=\dfrac{1}{2}\times b\times (4b-2)\\\\56=4b^2-2b\\\\28=2b^2-b\\\\b=4\ inches,-3.5\ inches[/tex]

Base = 4 inches

Height = 4(4)-2

= 14 inches

Hence, this is the required solution.

Answer:

x=2 and y=-6 aka. (2,-6) which is the point of intersection

Step-by-step explanation:

Use elimination to cancel out y by adding the equations:

5x=10

x=2

Plug x=2 into one of the equations and find y:

2(5)+2y=-2

10+2y=-2

2y=-12

y=-6

Therefore, x=2 and y=-6
